HUMIDI'FIER ATTACHMENT FOR CARBURETERS.

1,3 5 vgui` Specification of Letters Patent.

Application filed April 1,

To @Zlio/710m# may concern 5e it known that l, 'OnLxNn L. Inmo, acitizen oi the United States, residing at Los Angeles, in the county ot Los Angeles and State of:l California, have invented new and useful improvements in llumidilier Attache ments 'for Carbureters, of which the follow# ing is a specification. l

My ii vention relates to improvements in humidifier attachment for carbureters in which means isV provided for admitting water to the gaseous mixture passing through the carburetor to the engine cylinders and an object of my invention is to provide a liumidiiier attachment carrying a supply of water at a constant Vlevel yfrom which supply the water is drawn into the carbureter by the influence oi the air traihc through the carbureter; a second object being to so combine the humidifier attachment with the mixture passage of the carbureter that the amount of water drawn into the mixture will be governed by the volume of the mixture admitted to the cylinders.

rl`he invention consists of the novel features herein shown, described andclaimed.

Figure lis a side elevation of acarbureter in section and showing the attachment, em bodying the principles of my invention, inv section, and in working positionrelative to the carbureter.

Fig. 2 is an elevation of the devicepartly in section and looked at in the direction of the arrow 2, Fig. 1.

Fig. 3 is a top view of the humidifier and carbureter as shown in elevation in Figs. 1 and 2.

F ig. 4 is a horizontal sectional view of the humidifier and carbureter taken on the line 4 4, Fig. 1.

In carrying out my invention a carburetor 1 is provided comprising an air inlet passage 2, a fuel nozzle 3, a venturi 4, a mixture passage 5, 'and an auxiliary air passage 6.

At the side of the air passage is' positioned a fuel chamber in which is Amounted the conventional Jfuel bowl and lloat 7 for operating a needle valve (not shown)` The fuel enters the carburetor by the tube 8 and passes to the fuel nozzle 3 through the conduit 9. lVithin the mixture passage 5 and above the venturi is mounted a throttle valve 10.

Mounted above the fuel chamber 7 and Patented oet. 5,1920. 191s.. serial No. 226,101.

at the side of the mixture passage 5is a humidifier attachment 11, the details of which. are as follows:

' A water bowl or chamber 12 is provided in which is positioned a float 13. The chamber 12 is provided withy a cover 14 from which .depends an ear 15 carrying a pin upon which is pivotedfa lever 16 having a cross bar 17, the lever being operated vertically by the iloat 13 by means of the bar 17. In the cover 14 is formed a water inletv conduit 1S communicating with the chamber 12. A needle valve 19 is mounted upon the end of thc lever 16 and adapted to operate upon the water inlet orifice on the under side or" the cover 14, thus controlling theamount of water passing into the chamber 12.

Y The cover 14 is'alsoadapted to lit against the side of the mixture passage 5 and has a port 2O leading from about the center of the cover and connecting with a port out through the wall oi' the mixture passage 5 just below the seat of the valve 10. A glass 21 is positioned `above the outer terminus of the port 20 and is provided with la bonnet or valve litting 22 having al downwardly extending central nozzle 23. A valve 24 is mounted in the top of the bonnet 22 adapted to operate to govern the llow of fluid through the nozzle. connects the nozzle 23 with the chamber 12 below the water level thus forming a sight feed means for the water passing from the supply chamber 12 to the mixture passage 5.

A vent 26 is provided fpr the bonnet 22 and a. second vent 27 opens into the port 20 its opening being controlled by a valve 28.

The practical operation of the device is as follows: The valve 10 swings in the lpath of the dotted lines shown in Fig. 1 and in its opening swings across the port 20. Vhen the valve 1() is closed no water is drawn from the humidifier but as the valve is opened the port 20 begins to be exposed to the suction of the cylinders and water is drawn from the chamber 12 through the conduit 25 past the valve 24 issuing in sight from the nozzle 23 and passing into the mixture through the port 20.

Vhen the port 20 has been fully exposed to the air trailic by a further opening of the valve 10 the amount of water then drawn in with the mixture is governed by the speed A suction conduit 25V engine cylinders which volume is the only criterion of the amount of moisture required after a proper adjustment of the valve 24.

vention as set forth herein'in its preferred form without departing from the spirit of the invention, as claimed.

I claim: y Y

l. A humidifier attachment for carbureters comprising a water bowl, a float mounted Vin the bowl, a cap forming a cover for the bowl, a lever pivotally connected to thev cap and resting upon the ioat, a water supply passage formed in the cap having a downwardly extending terminus opening into -the bowl, and a needle valve mounted upon the free end of the lever pointing upwardly and adapted to operate to close the inner terminus of the water supply passage.

V2. A humidifier comprising a water bowl, a float operatively mounted in thebowl, a

' cap forming a cover for the water bowl, a

lever pivotally mounted above the float and 4resting upon the float, a boss formed integral with the cap, a water pipe tapped into the boss, there being a passage leading from the water pipe through the boss intoV the bowl, a valve seat surrounding the inner terminus of the passage, `and a valve controlling said valve seat, said valve being operatively connected to the free end of the lever. ,Y

3. A humidifier comprising a water bowl,

. a float operatively mounted in the bowl, a

Y cap forming a cover for .the water bowl, a lever pivotally mounted above the float and Vrestingpupon the float, a water supplyY passage lformed in the cap having an inner terminus opemnguinto the bowl the terminus being'surrounded by a valve seat, a plunger having a needle point fitting the valve seat, the lower end of the plunger being connected to the free end of the lever so as to control the flow of water into the bowl, a boss upon the cap and having a horizontal passage leading fromits outer end to the center of the cap and having an upturned end at the center of the cap, a seat around the upturned t. Aend of the passage, a glass tube upon the Various changes may be made in the in-` seat, a valve tting upon the glass tube, a valve in the valve itting for controlling an orice discharging downwardly at the center of the glass tube, a pipe extending from the valve fitting outwardly and downwardly through the cap and into the chamber of the water bowl, the lower end of the pipe being` below the water level, and means for connecting the outer end of the passage to the neck of a carbureter so as to discharge into the fuel mixture chamber below the throttle. v

4. A humidifier comprising a water bowl, a .lioat operated valve, means for supplying water to the water bowl controlled by said valve, a cap forming a cover for the water bowl, a boss upon the cap having a horizontal passage leading from its outer end to the center of the cap and having an upturned end at the center-,of the cap, a seat around the upturned end of the passage, a glass tube upon the seat, a valve fitting upon the glass tube, a valve in the valve litting for controllingv an orifice discharging downwardly at the center of the Glass tube, ,a pipe extending from the valve htting outwardly Vand downwardly through the cap and into the water bowl, the lower` end of the pipe being below the water level, and means for connectingtheouter end of the passage to the neck of the carbureter so as to discharge into the fuel mixture chamber below the low side of the throttle.l
